[roll] Roll fuchsia [fastboot][usb] Implement request batching for bulk transfers

Increase the number of concurrent USB requests in the fastboot function
driver from 1 to 16 to improve bulk transfer performance. Update the
transmit and receive queue logic to dispatch as many requests as
possible based on how much remaining data we have to transfer, rather
than waiting for individual requests to complete.

This seems to generally double throughput when flashing images on a
minimal product build. The speedup is not as great with an actual
recovery image, likely due to contention of other system resources, but
there still remains a notable performance improvement of 20-30%.
